In my quest to figure out my stalling issue I broke a vaccum line. Since these things are brittle as hell, and a couple spots have been patched in the past, I want to go and replace them with either a silicon or rubber/steel replacement. How do I go about doing this properly? can I reuse all the plugs and end fittings or will I need all new ones? Thanks!

good question but being vacume line i dont think you need stiffer ones i replaced all mine with some new vacume hose from advanced got 6 foot for $3.50 so cant complain there and runs alot better with new solid lines and for the one coming off the throttle body it was all flaky and had no replacement for it yet so i just wrapped it with electrical tape and a lil heat to make it leak proof lol.

Justin when I had my 91 cutlass supreme I too broke the brittle plastic vacuum lines. They do not come brittle but over the years age takes its toll and they do break easily. To replace them with rubber you can use the stock "T" and elbows. You need to break off a few 2" pieces of the plastic lines to use as connectors. Go to autozone and fine a rubber line that fits snug over the factory plastic lines. Use the factory vacuum line 2" pieces at junctions and elbows and slide the new rubber lines over them. I hope I am clear with what im trying to say...

yeah i used his method to so much faster but for looks id go with the braided ones if thats what you like lol. but plain old rubber vacume hose works great fast cheap

Ok, so I'm going to order the new hose. The stock hoses are 1/8" or 3mm. Should I go larger, say 3.5 or 4mm to get a good fitting on top of the old stuff? I planned on ordering a couple feet of each to make sure but if someone knows better than me I thought i'd ask.

Went back today, one of the regular (read intelligent) workers was there. Said I was looking for rubber hose and dam if they diddnt have about 20 different rolls in stock. Got one that fits perfetly. Much cheaper than the interwebs too.
